Abstract: There are mainly two traditional types of theories in inductive reasoning — similarity-based induction and category-based induction. The effect of category, especially the labels, has been gradually discovered in inductive reasoning during the two theories’ argument, but currently, there is a lack of systematicness in analyzing of different labels. Hence this article puts emphasis on the two major labels—linguistic labels and category labels, and then attempts to define their roles and relations, clarify the confusions from this perspective. Simultaneously, the author proposes the children’s cognitive models in inductive reasoning based on associations between the labels study and children’s language acquisition. In the end, the article asserts that the mechanism, technique, and the profound internal relationships should be concerned in future researches.

Key words: children, inductive reasoning, labels, linguistic labels, category labels
